GAS-BURNER ATTACHMENT F OR RANGES.

SPECIFICATION forming part of Letters Patent No. 576,795, dated February 9, 1897'.

Application filed January 27, 1396. Serial No. 576,975. (No model.)

To all whom it may concern.

Be it known that l, LOUIS STocKsrRoM, a subject of the Emperor of Germany, and a resident of the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Improvement in Gas-Burner Attachments for Ranges, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

forming part of this specification.

My invention relates to that class of combined cooking stoves or ranges in which there are attached to a coal or wood stove or range a set of gas-burners which when in use occupy the top of the'stove or range and which when not in use are turned up out of theway, so that the stove or range may be used in the ordinary way.

My invention consists in features of construction and arrangement hereinafter fully described, and pointed out in the claims.

Figure I is a top or plan View, part in section, illustratingmy invention, the section being taken on lineI I, Fig. II. Fig. II is a front elevation. Fig. IIlisaside elevation. Fig. IV

is an enlarged detail View showing part of the frame of the gas-burners and showing one of the mixing-chambers. Fig. V is an enlarged View showing the gas-burn er frame folded and in its lower'position. Fig. VI is a similar view showing the gas-burner frame folded and turned up away from the top of the range, so as to'perlnit the range to be used as an ordinary coal or wood range. Fig. VII is an enlarged detail vertical section taken on line VII VII, Fig. I. Fig. VIII is a detail bottom plan View of that shown in Fig. IV. Fig. IX is a perspective view of that shown in Fig. VII.

Referring to the drawings, 1 represents the top of an ordinary coal stove or range. It has an elevated overhanging warming-oven '2, supportedon an end wall 4 and side walls 5, forming a housing into which the gas-burning apparatus can be turned when the range is to be used as an ordinary coal-range.

6 represents the stovepipe of the range.

To the top of the range is secured a gasburning apparatus consisting of a two-part frame 7, hinged together at 8. This frame is provided with a number of ordinary gas-burners '7 having the usual mixing tubes or chambers 9. The inner section of the frame7 is connected to the top of the range by hinges 10, the pintle of which is a gas-pipe 11. The pipe 11 has branches 12 and 13, which are 5 5 supplied with the usual gas valves and jets 14, one for the mixing-chamber 9 and each burner '7.

15 represents the pipe through which gas is supplied to the pipe 11, and between the pipe 15 and the pipe 11 is a joint 16, which does not interfere with the turning of the pipe 11, but at the same time forms a gas-tight union between the two pipes. The form of this joint is not shown, as its construction is well known to mechanics, and it may be such as is used on the ordinary well-known turn-downtank gasolene-stoves on the market.

When the frame 7 is turned down on top of the range, it is used as any ordinary gasstove is used. It is supported slightly above the top of the range by means of short legs 17, having feet 17*.

When it is desired to use the range for cooking purposes, it is turned up into the 7 housing 4 5, beneath the housing, out of the way, thus exposing the entire top of the range. To avoid having the warming-oven at an undesirably high elevation, I hinge the frame 7 at 8, as previously stated, and so construct the parts that the outer section of the frame may be folded over onto the inner section, as shown in Fig. V, and then thetwo sections turn up on the hinges 10, as shown in Fig. VI. The branches 12 and 13 of the pipe 11 are secured to the inner sec-' tion 7 of the frame and do not interfere with the folding of the outer section onto the inner section, but inasmuch as the outer valves and jets 14 must be carried by the branches o 12 and 13 and the mixing-chambers 9 must be carried by the outer section of the frame 7, and inasmuch as the inner ends of the jets must extend into the mixing-chambers when the apparatus isin position'for use, it be 5 comes necessary to notch out the sides of the two outer mixing-chambers 9, as shown at 18, Figs. IV and VIII, so that as the outer section of the frame 7 is turnedover onto the inner section the mixing-chambers 9 will 10o pass the jets 14.

19 represents a pan having grooved flanges 20 011 the upper side thereof and placed on the top of the range and receiving the feet 17' of the inner and middle legs 17 of the frame 7, as shown in Figs. VII and IX. This pan, when the frame 7 is down in using position, rests on top of the range and may be pulled forward, so as to be beneath all of the burners 7, and thus protect the top of the range from being soiled. hen the frame 7 is turned up into non-using position, the plate is lifted with it, and 19 forms a front to the housing 4 5, as shown in dotted lines in Fig. VI, thus hiding the gas-burning apparatus and giving the range a neat appearance.

21 represents a branch extending from the pipe 15 to the warming-oven 2, where it is provided with a valve and burner for heat ing the warming-oven when desired.

I claim as my invention 1. A gas-burning attachment f r ranges comprising a turning gas-pipe, a frame having inner and outer sections provided with burners and hinged together so as to fold the outer section upon the inner sect-ion, hinges whereby the frame is connected to the turning gas-pipe, the gas-pipe branches having valves and connected to the turning gaspipe, secured to the inner section and adapted to be raised and lowered with the frame;

substantially as described.

2. A gas-burning attachment for ranges comprising a turning gas-pipe, a frame havl ing burners, hinges whereby the frame is connected to the turning gas-pipe, the gaspipe branches having valves, and connected to the turning gas-pipe, secured to the frame and adapted to be raised and lowered with the frame, and a pan secured to the bottom of the frame, sliding on the latter and adapted to provide a front plate for the frame when it is elevated; substantially as described.

In combination with a range having a housing, a frame provided with gas-burners and hinged to the range within the housing, and a sliding pan secured to the bottom of the frame and providing a front plate to the housing for concealing the frame; substan tially as described.

4. A gas-burning attachment for ranges comprising a turning gas-pipe, a frame having inner and outer sections provided with burners and mixing-chambers and hinged together, hinges whereby the frame is connected to the turning gas pipe, the gas -pipe branches provided with valves, and connected to the turning gas-pipe, secured to the inner section, and adapted to be raised and lowered with the frame; the mixing-chambers of the outer section having notches to permit the outer section to be folded upon the inner section; substantially as described.
